my $results = Mojo::Pg::Results->new(sth => $sth);
$results->hashes->map(sub { $_->{foo} })->shuffle->join("\n")->say;

DESCRIPTION

Mojo::Pg::Results is a container for DBD::Pg statement handles used by Mojo::Pg::Database.

ATTRIBUTES

Mojo::Pg::Results implements the following attributes.

db


            

              
              
my $db   = $results->db;
$results = $results->db(Mojo::Pg::Database->new);

Mojo::Pg::Database object these results belong to.

sth


            

              
              
my $sth  = $results->sth;
$results = $results->sth($sth);

DBD::Pg statement handle results are fetched from.

METHODS

Mojo::Pg::Results inherits all methods from Mojo::Base and implements the following new ones.

array


            

              
              
my $array = $results->array;

Fetch one row from "sth" and return it as an array reference.

arrays


            

              
              
my $collection = $results->arrays;

Fetch all rows from "sth" and return them as a Mojo::Collection object containing array references.


            

              
              
# Process all rows at once
say $results->arrays->reduce(sub { $a + $b->[3] }, 0);

columns


            

              
              
my $columns = $results->columns;

Return column names as an array reference.


            

              
              
# Names of all columns
say for @{$results->columns};

expand


            

              
              
$results = $results->expand;

Decode json and jsonb fields automatically to Perl values for all rows.


            

              
              
# Expand JSON
$results->expand->hashes->map(sub { $_->{foo}{bar} })->join("\n")->say;

finish


            

              
              
$results->finish;

Indicate that you are finished with "sth" and will not be fetching all the remaining rows.

hash


            

              
              
my $hash = $results->hash;

Fetch one row from "sth" and return it as a hash reference.

my $collection = $results->hashes;

Fetch all rows from "sth" and return them as a Mojo::Collection object containing hash references.


            

              
              
# Process all rows at once
say $results->hashes->reduce(sub { $a + $b->{money} }, 0);

new


            

              
              
my $results = Mojo::Pg::Results->new;
my $results = Mojo::Pg::Results->new(sth => $sth);
my $results = Mojo::Pg::Results->new({sth => $sth});

Construct a new Mojo::Pg::Results object.

rows


            

              
              
my $num = $results->rows;
